Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a display control device for simultaneously displaying a plurality of input images on one screen, a display control method in the display control device, and a program executed by the display control device.
[0002]
[Prior art]
In digital television broadcasting, a broadcaster uses a kind of relatively high-definition video content called HD (High Definition) in a transport stream (TS) for one channel, or is called SD (Standard Definition). It is possible to multiplex a plurality of types of video contents of lower image quality than the HD video and broadcast.
[0003]
Here, in the case where a plurality of SD video contents are multiplexed as described above, the receiving device receiving the plurality of SD video contents is configured to be able to receive a TS for one channel. Video contents can be received simultaneously. With the improvement in decoding capability in recent years, it is sufficiently considered that a plurality of video images received in this manner can be simultaneously decoded and these decoded video images can be simultaneously displayed and output on one screen. Can be
[0004]
In recent digital television broadcasting, a service called a multi-view television has been developed by utilizing a system for multiplexing a plurality of SD images into one channel as described above.
The multi-view television is a service in which, for example, a plurality of SD videos having contents related to each other and audio and data broadcasts attached thereto are grouped and broadcasted to one channel of TS. With this service, it is possible to simultaneously provide a plurality of video contents obtained by photographing the same subject from multiple angles as contents of one broadcast channel (so-called multi-angle broadcasting) for a baseball broadcast or the like. It becomes.
[0005]
[Problems to be solved by the invention]
In view of the above, when a channel providing a service as a multi-view television is received, a plurality of received SD images may be displayed simultaneously on one screen.
[0006]
However, the configuration of a multi-view television including a plurality of videos may be different depending on the content of each video.
For example, in part, the videos that make up a multi-view television are not individual but different in content. In accordance with this, for example, with respect to a plurality of videos forming a multi-view television, for example, a configuration in which one video is a main video and another video is a sub video can be standardized.
[0007]
It is also conceivable that the number of videos constituting the multi-view television will differ.
For example, assuming that three SD videos are transmitted on one channel, all three videos may form one multi-view television, or only two videos may form one multi-view television group. However, it is conceivable that the remaining one image has completely different content from the image of the multi-view television.
[0008]
Also, a plurality of videos constituting the multi-view television are not necessarily the same aspect ratio, and different aspect ratios may be set according to, for example, contents. Also, even if the aspect ratio is the same, some patterns are conceivable as components viewed from the aspect ratio, such as 4: 3 or 16: 9.
[0009]
In this way, the configuration of the multi-view television may differ, for example, for each program. In such a case, for example, if a plurality of videos are simply displayed simultaneously according to a certain rule, the layout of the video may be such that the main / sub relationship between the videos and the aspect ratio relationship are ignored. Comes out.
In such a case, for example, a layout that does not match the content of the video may make it difficult for the user to grasp the flow of the content of the video. Also, depending on the aspect ratio relationship between the images, there is a sufficient possibility that the entire display screen will be unbalanced and unnatural.
[0010]
In view of this, for example, when simultaneously displaying a plurality of videos forming a multi-view television, it is not necessary to simply simultaneously display a plurality of videos on the same screen in accordance with a certain rule. It can be said that it is preferable to perform simultaneous display with an appropriate layout pattern based on the configuration of the video in the multi-view television.
[0011]
[Means for Solving the Problems]
In view of the above problems, the present invention is configured as follows as a display control device.
That is, first, an input means for inputting a plurality of video signals, and a video signal processing means for performing required video signal processing for video display on the plurality of video signals input by the input means. I do.
And, for a video signal group composed of the plurality of video signals input by the input means, a determination means for determining the configuration pattern, further, according to the configuration pattern determined by the determination means, Determining means for determining a layout pattern for simultaneous display on one screen of the plurality of video signals, and the video signal so that video display is performed in a display mode corresponding to the layout pattern determined by the determining means. Control means for controlling the processing means.
[0012]
Further, according to the present invention, a display control method is as follows.
That is, first, for a video signal group composed of a plurality of input video signals, a discriminating process of discriminating the constituent pattern is executed, and then, according to the constituent pattern determined by the discriminating process, The determination processing for determining a layout pattern for simultaneous display on one screen of the plurality of video signals, and the video display in a display mode corresponding to the layout pattern determined by the determination processing is performed. And a control process for controlling a video signal processing operation for displaying and outputting a plurality of video signals.
[0013]
Further, according to the present invention, the program is configured as follows.
That is, for a video signal group composed of a plurality of input video signals, a discriminating process of discriminating the constituent pattern, and one screen of the plurality of video signals according to the constituent pattern discriminated by the discriminating process. Determining processing for determining a layout pattern for simultaneous display above, and displaying and outputting the plurality of video signals so as to perform video display in a display mode corresponding to the layout pattern determined by the determining processing. The control processing for controlling the video signal processing operation is executed by the display control device.
[0014]
According to the present invention, for a plurality of input video signals, for example, the configuration pattern of the video signal group due to the number of the videos, the presence or absence of relevance between the videos, the difference in the aspect ratio of each video, and the like. Is determined. Then, a layout pattern for simultaneously displaying the plurality of video signals on one screen is determined according to the configuration pattern of the video signal group. Then, the video signal processing operation for displaying and outputting the plurality of video signals is controlled so that the video display is performed in the display mode corresponding to the layout pattern determined in this way.
Thus, according to the present invention, an optimal layout pattern corresponding to a configuration pattern of a video signal group due to, for example, the number of videos, the presence or absence of relevance between the videos, and the difference in the aspect ratio of each video. Thus, a plurality of input video signals can be displayed.
[0015]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments will be described by taking as an example a case where the display control device of the present invention is applied to a digital satellite broadcast receiver configured to be able to receive a broadcast signal in digital satellite broadcast.
FIG. 1 is a block diagram showing an example of the internal configuration of a digital satellite broadcast receiver 1 according to the present embodiment.
First, the digital satellite broadcast receiver 1 shown in FIG. 1 receives a broadcast signal received by a parabolic antenna 20 and converted into a predetermined high-frequency signal by an LNB (Low Noise Block Down Converter) built in the parabolic antenna 20. Will do.
[0016]
In this case, the broadcast signal usually includes only one video content called HD (High Definition). Further, under this digital satellite broadcasting standard, it is possible to multiplex and broadcast a plurality of SD (Standard Definition) video contents in one channel (service).
Further, in the case where a plurality of SD video contents are multiplexed in one channel in this way, as a so-called multi-view television video content, at least two or more related contents are included and broadcast. May be done.
As described above, the multi-view television refers to a service in which a plurality of SD video contents (including audio and other data) having related contents are grouped according to the contents and broadcast.
[0017]
In the digital satellite broadcast receiver 1, in order to cope with the case where a plurality of video contents are multiplexed on one channel as described above, a plurality of received SD video contents are simultaneously decoded by an MPEG decoder 5 shown in the figure. It is possible to decode. The decoded video can be simultaneously displayed and output on one screen by the video signal processing unit 6 also shown.
[0018]
1, in the digital satellite broadcast receiver 1, a reception signal received by the parabolic antenna 20 and converted into a predetermined frequency is input by a front end unit 2.
The front end unit 2 receives a carrier (reception frequency) determined by the setting signal based on a setting signal from the system controller 10 connected via the internal bus 9 and setting transmission data and the like. For example, a TS is obtained by performing a Viterbi demodulation process, an error correction process, or the like.
[0019]
As is well known, the TS according to the digital satellite broadcasting standard includes, for example, compressed data obtained by compressing video signals and audio signals of a plurality of programs (video programs) by MPEG2 (Moving Picture Experts Group Layer 2), and various additional data. Information is multiplexed.
[0020]
The compressed data obtained by compressing the video signal and the audio signal are multiplexed as an ES (Elementary Stream). The additional information inserted by the broadcasting side includes PSI (Program Specific Information) storing tables such as PAT (Program Association Table) and PMT (Program Map Table), and SI (Service Information: Program Information). ).
The above information is multiplexed by forming a TS by a transport stream packet (TS packet) of 188 bytes and storing the ES and the various additional information described above in the TS packet. Done.
The TS obtained by the front end unit 2 is supplied to a descrambler 3.
[0021]
Further, the front end unit 2 acquires a PSI (Program Specific Information) packet from the TS, updates the channel selection information, and obtains a component PID (Program ID) of each channel in the TS. For example, it is transmitted to the system controller 10. In the system controller 10, the acquired PID is used for reception signal processing.
[0022]
Here, as described above, in the case of the present embodiment, a plurality of SD video contents may be multiplexed in a received TS for one channel (hereinafter, referred to as a partial TS). In such a case, the packet corresponding to the plurality of video contents is specified by the PID. In other words, the digital satellite broadcast receiver 1 determines the type of the video content multiplexed in the partial TS as described above based on the acquired PID.
Similarly, when the plurality of received video contents are video of a multi-view television, the grouping of the video content of the multi-view television is performed by a component group in an EIT (Event Information Table). It will be indicated by the identifier. That is, in this case, by referring to the component group identifier, it becomes possible to determine the grouped video contents among the plurality of received video contents.
[0023]
In the descrambler 3, the descramble key data prepared in advance is received from the system controller 10 via the internal bus 9, and the PID is set by the system controller 10. Then, a descrambling process is executed based on the descrambling key data and the PID.
[0024]
The demultiplexer 4 separates necessary TS packets from the TS supplied from the descrambler 3 according to the filter conditions set by the system controller 10 connected via the internal bus 9. As a result, in the demultiplexer 4, for example, a TS packet of video data compressed by the MPEG2 system and a TS packet of audio data compressed by the MPEG2 system, for example, as a video program, You will get. Then, the compressed video data and compressed audio data thus obtained are output to the MPEG decoder 5.
[0025]
It should be noted that, for confirmation, the above-described setting of the filter condition is performed by the system controller 10 based on the information content described in the PAT, PMT, PID, and the like included in the TS. In particular, in the case of the present embodiment, when a plurality of video contents are multiplexed in the partial TS, the compressed video data and the compressed audio data of each video content are determined based on the filter condition based on the PID and the like. To get
The individual packets of the compressed video / audio data separated by the demultiplexer 4 and input to the MPEG decoder 5 are input to the MPEG decoder 5 in a format called PES (Packetized Elementary Stream). I have.
[0026]
The MPEG decoder 5 includes a video decoder that decodes (decompresses) compressed video data according to the MPEG2 format and an audio decoder that decodes compressed audio data according to the MPEG2 format in synchronization with the video data output. It has. Then, the input compressed video data is decoded by a video decoder, and the input compressed audio data is decoded by an audio decoder.
In this case, the MPEG decoder 5 decodes and outputs the compressed data at the same time by performing, for example, time-divisional decoding processing of the plurality of input compressed video data and the plurality of compressed audio data. It is configured to be possible. Alternatively, a configuration may be adopted in which a video decoder and an audio decoder are provided in parallel in correspondence with the plurality of input compressed video data and compressed audio data.
Further, in the MPEG decoder 5, information on the aspect ratio of each video obtained at the time of performing the decoding process is supplied to the system controller 10.
The decoded video data is supplied to the illustrated video signal processing unit 6, and the audio data is supplied to the audio signal processing unit 7.
[0027]
The video signal processing unit 6 superimposes a plurality of video data supplied from the MPEG decoder 5 so that a display mode based on the display layout pattern specified by the system controller 10 is obtained.
Then, the video data thus superimposed is subjected to required signal processing to obtain a video signal for external output, and then supplied to the display 21 shown in the figure.
When only one video content is included in the TS, the video signal processing unit 6 outputs the video data supplied from the MPEG decoder 5 as an external output under the control of the system controller 10 as it is. 21.
[0028]
The audio signal processing section 7 performs necessary signal processing on the audio data supplied from the MPEG decoder 5 as described above to obtain an audio signal for external output. The audio signal thus obtained is supplied to the speaker 22.
[0029]
The system controller 10 executes various control processes so that a required operation in the digital satellite broadcast receiver 1 is obtained, as understood from the above description.
For example, the system controller 10 sets filter conditions for the demultiplexer 4 based on the information content described in the PAT, PMT, PID, and the like extracted from the reception TS as described above. In particular, in the case of the present embodiment, display control processing or the like is performed according to the number of video contents included in the partial TS. The processing operation according to the present embodiment will be described later.
[0030]
The system controller 10 is provided with a ROM 11 and a RAM 12 as shown.
The ROM 11 stores programs to be executed by the system controller 10 to implement the various control processes described above, and various types of initial setting information. In particular, in the case of the present embodiment, the ROM 11 also stores a program for realizing a display control operation as shown in FIG. Further, a display layout table 11a, which is necessary for performing this display control operation as described later, is also stored.
Further, the RAM 12 appropriately holds data necessary for the system controller 10 to execute various control processes.
[0031]
The operation unit 8 is connected to the system controller 10. The operation unit 8 is provided with various operators for performing operations on the digital satellite broadcast receiver 1. Then, operation signals corresponding to the operations performed on these operators are output to the system controller 10. The system controller 10 executes necessary control processing so that an operation corresponding to the input operation command is obtained.
Note that, in addition to the operation unit 8, a user interface unit using, for example, a remote controller or the like may be provided.
[0032]
Here, as described above, the digital satellite broadcast receiver 1 shown in FIG. 1 may receive a plurality of video contents as broadcast contents for one channel. In response to this, the digital satellite broadcast receiver 1 is configured to be able to simultaneously display a plurality of such received images on the display 21.
In the present embodiment, a plurality of images to be simultaneously displayed on one screen are displayed and output with an optimal display layout according to these configuration patterns. For this purpose, in the digital satellite broadcast receiver 1, by referring to the display layout table 11a stored in the ROM 11 as described above, the digital satellite broadcast receiver 1 corresponds to the configuration pattern of a plurality of received videos. Information of an optimal display layout is obtained.
[0033]
FIG. 2 is a data structure diagram showing the structure of the display layout table 11a stored in the ROM 11 as described above.
In this figure, for convenience of explanation, the actual configuration pattern of a plurality of videos multiplexed in the partial TS is schematically shown in the column labeled "Configuration" in the leftmost column in the figure. . In the column of “composition”, “A”, “B”, and “C” shown in the figure indicate the respective images to be multiplexed in the partial TS and their priorities (that is, A has the highest priority, B, C, and C). Are sequentially followed by a circle), and those with circles indicate that they are grouped as multi-view television images.
[0034]
In FIG. 2, the display layout table 11a includes the number of videos multiplexed in the partial TS, the number of videos on the multi-view television, the default video (A video), the B video, Data on each item of the aspect ratio of each video of the C video is written.
The default video (A video) is a video set as the highest priority when the broadcaster multiplexes a plurality of videos as a one-channel service. The digital satellite broadcast receiver 1 is configured to output audio corresponding to the default video when outputting the received video content.
The B video and the C video have a lower priority than the default video.
The distinction between the default video, the B video, and the C video is indicated, for example, in the order of description of items indicating each video in the EIT.
[0035]
In the display layout table 11a shown in FIG. 2, the information on the number of videos, the number of videos on the multi-view television, and the aspect ratio of each video is used as information indicating a configuration pattern of a plurality of videos multiplexed in the partial TS. As shown, these form one set of configuration information.
Further, as described above, the information of the layout pattern is associated with the respective configuration information indicating the configuration pattern of the video, as shown in the figure.
For example, as shown at the top of the display layout table 11a, the information on the number of videos is “2”, the information on the number of videos on the multi-view television is “2”, and the information on the aspect ratio of each video is all “4: As shown in the drawing, the configuration information “3” is associated with the pattern “1” as the layout pattern information.
[0036]
In this manner, in the present embodiment, as a display layout pattern corresponding to each configuration information as information indicating a configuration pattern of a video multiplexed in the TS, for example, as shown in the following FIGS. Is assumed.
First, FIG. 4 shows an example of a display layout corresponding to each of the layout patterns 1 to 3 shown in FIG.
First, as can be seen with reference to FIG. 2, these layout patterns 1 to 3 correspond to the case where the aspect ratios of the respective images multiplexed in the TS are all 4: 3. In this embodiment, for example, a display mode as shown in FIG. 4A is obtained as layout pattern 1 corresponding to a case where two images are multiplexed.
That is, as shown in the figure, for example, a default image (A image) and a B image are displayed side by side with the same image size.
[0037]
The layout pattern 2 and the layout pattern 3 correspond to a case where three videos are multiplexed assuming that all the videos are 4: 3. Then, as shown in FIG. 2, the layout pattern 2 corresponds to a case where the three images are all multi-view television images and a case where all of the three images are not multi-view television images.
As a display mode according to the layout pattern 2, as shown in FIG. 4B, for example, a default image is arranged in a relatively large image size, and, for example, a B image and a C image are displayed side by side vertically. And
[0038]
Further, as can be seen with reference to FIG. 2, the layout pattern 3 has an aspect ratio of all three pictures of 4: 3 as described above. For example, only the default picture and the B picture are grouped by a multi-view television. It corresponds to the case where it has been converted.
As the layout pattern 3, as shown in FIG. 4C, for example, both a default image and a B image are arranged in a relatively large image size, and a C image, which is not a multi-view television image, is compared with a relatively small image. Arrange according to size.
[0039]
Subsequently, FIG. 5 shows an example of a display layout corresponding to each of the layout patterns 11 to 13 shown in FIG.
These layout patterns 11 to 13 correspond to the case where the aspect ratios of the respective images multiplexed in the TS are all 16: 9 as shown in FIG.
Among them, the layout pattern 11 corresponds to a case where two images are multiplexed, and in response to the layout pattern 11, a display mode as shown in FIG. To
In other words, as shown in FIG. 5A, for example, the default video (A video) and the B video are displayed vertically in the same image size.
[0040]
Further, as shown in FIG. 2, the layout patterns 12 and 13 correspond to a case where three videos are multiplexed in a TS among 16: 9 video images. When all three images are multi-view television images, and when all three images are not multi-view television images, the layout pattern 12 is made to correspond.
In response to the layout pattern 12, for example, as shown in FIG. 5B, a default image is arranged in a relatively large image size, and B images and C images are arranged horizontally, for example, below or above it. To do.
[0041]
The layout pattern 13 corresponds to a case where the aspect ratio of three videos in the TS is 4: 3, and only the default video and the B video are grouped by the multi-view television.
In response to the layout pattern 13, for example, as shown in FIG. 5C, both the default image and the B image are arranged in a relatively large image size, and the C image which is not a multi-view television image is compared. Arrange them according to the target image size.
[0042]
FIG. 6 shows an example of a display layout corresponding to each of the layout pattern 21 and the layout pattern 22 shown in FIG.
The layout pattern 21 and the layout pattern 22 correspond to the case where the aspect ratio of each video multiplexed in the TS is different from each other.
As a case where the aspect ratios of the respective images are different from each other, for example, when the aspect ratio of the default image is 16: 9 and the aspect ratio of the B image and the C image is 4: 3, for example, FIG. A layout pattern 21 as shown in FIG.
That is, for example, the default video is arranged with a relatively large image size, and the B video and the C video are arranged side by side below or above the default video.
[0043]
For example, when the aspect ratio of the default video is 4: 3, the aspect ratio of the B video and the C video is 16: 9, and the C video is not grouped by the multi-view television broadcast, Corresponds to the layout pattern 22 shown in FIG. 6B, for example.
That is, as shown in the figure, for example, the default video and the B video grouped by the multi-view television broadcast are arranged vertically in a relatively large image size, and the C video is arranged in a relatively small image size in the margin. Is to do so.
[0044]
In this way, by setting in advance the display layout pattern corresponding to each of the constituent patterns of the received plurality of videos, it is easier to display each video on one screen according to a certain rule, for example, An appropriate display mode is obtained in consideration of the aspect ratio and the relevance of each video.
[0045]
After preparing the display layout table 11a as described above, in the present embodiment, when a plurality of videos are multiplexed in the partial TS, first, information for grasping the configuration pattern of these videos is used. To get. That is, information on the number of videos multiplexed in the partial TS, the number of videos on the multi-view television, and the aspect ratio of each video is acquired as the above-described configuration information.
Then, by referring to the display layout table 11a based on the configuration information acquired in this way, the information of the corresponding display layout pattern is obtained.
Then, in accordance with the information of the corresponding display layout pattern obtained in this way, by superimposing each of the received videos in one screen, the optimum corresponding to the configuration pattern of these videos It is intended to obtain a display mode with a simple display layout.
[0046]
A processing operation to be performed by the system controller 10 shown in FIG. 1 to realize such an operation will be described with reference to a flowchart of FIG. The processing operation shown in this figure is executed by the system controller 10 based on the program stored in the ROM 11 shown in FIG.
3, first, the system controller 10 monitors that the section information added to the received TS is updated by the process of step S101 illustrated. That is, by monitoring the updating of the section information such as PAT, PMT, and EIT added to the TS in this manner, for example, when the receiving channel is switched, and at the same channel, multiple SD images are multiplexed. This is to monitor the point in time at which the state is switched between the broadcast state and the state where only one HD (High Definition) image is broadcast.
[0047]
If the section information is updated and the channel or broadcast is switched as described above, it is determined in step S102 whether a plurality of video contents are included in the partial TS.
The process of step S102 is performed by recognizing the number of types of video packets and audio packets, for example, indicated by the acquired information of the PMT. Then, as a result of this recognition, when it is determined that only one video content is included in the partial TS, the process proceeds to step S103 as illustrated, and the normal Execute screen output. That is, control is performed so that video data from the MPEG decoder 5 shown in FIG. 1 is output to the display 21 as it is via the video signal processing unit 6. Then, when the normal one-screen output is executed in this way, the process of step S101 is executed again.
[0048]
On the other hand, if it is determined by the determination processing in step S102 that a plurality of video contents are included in the partial TS, information on the number of videos of the plurality of videos is obtained in step S104. That is, as described above, by recognizing the number of types of video packets and audio packets indicated by the acquired PMT information, the information on the number of videos included in the reception TS is obtained. Things.
[0049]
In the following step S105, the priority of each video is recognized. In other words, based on the acquired EIT information, it recognizes the default video (A video), B video, and C video.
[0050]
In step S106, it is determined whether or not there is a video of the multi-view television in the partial TS. If it is determined in step S106 that the acquired EIT includes component group descriptor information indicating the grouping of each video and that the TS includes a multi-view TV video, the process proceeds to step S106. Proceed to S107. Then, in step S107, the information of the number of videos of the multi-view television is obtained from the information of the component group descriptor, and then the process proceeds to step S108.
On the other hand, in step S106, for example, when it is determined that the information of the component group descriptor does not exist in the EIT and there is no video of the multi-view television in the reception TS, the process proceeds to step S108. That is, even when the service is not a multi-view television, a plurality of videos may be multiplexed and broadcast on one channel.
[0051]
In step S108, information on the aspect ratio of each video recognized by the processing in step S105 is acquired. In this case, as described above with reference to FIG. 1, information on the aspect ratio of each video is supplied from the MPEG decoder 5.
At present, according to the digital satellite broadcasting standard, information on the aspect ratio of each video is described as a component type in a component group descriptor. For this reason, when all of the above images are multi-view television images, information on the aspect ratio of each image may be obtained from the description in the component type.
[0052]
In the subsequent step S109, all of the information on the number of videos acquired as described above, the information on the number of videos on the multi-view television, and the information on the aspect ratio of each video (that is, the configuration information described in FIG. 2) are used. Next, the display layout table 11a is referred to.
Then, in the subsequent step S110, in the display layout table 11a, information of a layout pattern associated with the acquired configuration information is acquired, and information of the layout pattern acquired in this manner is acquired. Is set in the video signal processing unit 6.
Accordingly, the video signal processing unit 6 performs an operation of superimposing each video so as to obtain a display mode based on the layout pattern set as described above. As a result, these images are displayed and output on the display 21 shown in FIG. 1 in a display mode based on the layout pattern.
That is, each video is displayed with an optimal display layout corresponding to the configuration of the video multiplexed in the partial TS.
[0053]
As described above, in the digital satellite broadcast receiver 1 according to the present embodiment, the number of images, the number of images of the multi-view television, and the aspect ratio of each image are determined for a plurality of images to be simultaneously displayed on one screen. A layout pattern corresponding to the composition pattern of each video, which is characterized by different ratios, is prepared.
In addition, when the received partial TS includes a plurality of video contents, a layout pattern corresponding to the configuration pattern of the plurality of videos is selected, and each video is displayed in a display mode according to the layout pattern. Is displayed and output.
[0054]
Thereby, depending on the present embodiment, each video is included in one screen by an optimal display layout according to the number of videos multiplexed in the partial TS, the relevance of each video, and the aspect ratio. It can be displayed.
[0055]
In addition, in the digital satellite broadcast receiver 1 side, each video multiplexed in the partial TS is displayed in an optimal layout on one screen, so that the broadcaster of the video content can As described above, it is possible to create a content on the premise that each multiplexed video is displayed with an optimal layout on the receiver side. In other words, depending on the digital satellite broadcast receiver 1 of the present embodiment, it is possible to greatly increase the degree of freedom of content production on the broadcaster side, for example.
[0056]
In the present embodiment, the case where the display control device of the present invention is applied to the digital satellite broadcast receiver 1 has been described as an example. However, other examples of the display control device of the present invention include, for example, the ground. The present invention may be applied to a receiver or the like configured to receive wave digital broadcasting.

Further, in the present embodiment, an example has been described in which a plurality of videos multiplexed in the partial TS are simultaneously displayed in one screen. However, in the case where a plurality of videos are simultaneously displayed on one screen in this way, a plurality of video contents over a plurality of channels are simultaneously received, and each video is displayed and output according to a layout pattern according to the configuration of these videos. You may make it.
By doing so, it is possible to give the user an opportunity to select a new program in digital broadcasting in which the number of services is expected to increase in the future.
Further, the case where a plurality of videos are multiplexed in one channel as described above may correspond to the case where three or more video contents are multiplexed.
[0058]
Further, the layout of each video displayed by the processing operation shown in FIG. 3 and the initially output audio need not be fixed to a preset one, and the layout and output of each video should be operated. The configuration may be such that switching of audio is possible.
In this case, the layout of each video and the output audio can be switched based on the user's request, so that the degree of freedom in viewing the video content by the user can be increased. For example, when a sports broadcast multi-angle broadcast or the like is received, the video of interest is displayed at an arrangement position of a large image size, and the audio output corresponding to the default video is switched to the audio output corresponding to this video. It is also possible.

【The invention's effect】
As described above, in the present invention, first, for a plurality of input video signals, for example, the number of video signals, the presence or absence of relevance between each video, and the difference in the aspect ratio of each video, etc. The configuration pattern is determined. In addition, a layout pattern for simultaneously displaying the plurality of video signals on one screen is determined according to the configuration pattern of the video signal group. Then, the video signal processing operation for displaying and outputting the plurality of video signals is controlled so that the video display is performed in the display mode corresponding to the layout pattern determined in this way.
Thereby, according to the present invention, for example, an input is made with an optimal layout pattern corresponding to the number of videos, the presence / absence of association between the videos, and the configuration pattern due to the difference in the aspect ratio of each video. It is possible to display a plurality of video signals.
[0060]
As described above, it is possible to display each video with an optimal layout corresponding to a configuration pattern of a plurality of input video signals, and thus, for example, the content of the content in which the relevance of each video described above is considered is considered. A display mode that is easy to grasp or a well-balanced display mode in consideration of the aspect ratio of each video can be obtained, so that user convenience can be improved.
